Natasha2012 [34]

Answer:

<em>The number of fish would decrease.</em>

Explanation:

Ecological hypoxia can be described as a condition in which the oxygen level drops to such low levels in the aquatic ecosystem that it is no longer able to support aquatic life. In such a condition, the number of fishes declines at a rapid rate because fishes require oxygen as an essential element. Also, those fishes which do not have better adaptations to survive might get totally wiped out from the aquatic ecosystem.

Which of the following represents organisms in a food chain?
Lisa [10]

Answer: c seeds, mice, snakes

Explanation:

<u>a hawks, owls, eagles NO</u>

These animals all eat some form of meat, and they are on the top of all of their food chains. If you put these animals in a room with no food, there'd be no food chain, and they would got out at each other until there was one left, and there'd be no advatanges because 1. they can all fly and 2. they are all top consumers. The same thing goes for D except hyenas can't fly.

<u>b deer, rabbits, cows NO</u>

This is not a food chain because all of the animals are herbivore, so they only eats plants and will not eat each other.

<u>c seeds, mice, snakes YES</u>

The seeds are a producer which is to be eaten by a consumer (the mouse), and which are then eaten by the predator, the snake.

<u>d hyenas, vultures, crows NO</u>

<u />

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
